Software tool identifies RF spectrum IMD frequencies

Launched by Kaltman Creations LLC, RF-intermodPRO is new software product that aids in calculating, predicting and identifying intermodulation interference of wireless devices.

The PC-based product refines and simplifies the process of identifying intermodulation distortion (IMD) frequencies in a given RF spectrum. It is available as a standalone PC-based software product or as a plug-in option for the Invisible WavesTM RF Command Center. The intermod software is designed for professional audio wireless microphone users, AV installers of wireless devices, frequency coordinators, and broadcasters.

Intermodulation distortion is created when two or more transmission frequencies mix together and form new additional signals. Sometimes referred to as 'spurious emissions', these newly created frequencies are harmonic as well as the sum and difference of the original frequency. And, these newly generated frequencies may be strong enough to cause interference to any transmitter that tries to occupy the same RF-spurious emissions space.

The new RF-intermodPRO graphically displays onscreen the predicted locations of these intermod components and assists in the frequency coordination process. Based on the user’s selection of transmitter models from a device library or custom inventory list, the software will advise the user on the best selection of transmitters/frequencies.

Additionally, based on zip code entry, the software automatically defines and identifies unusable RF spectrum spaced around local DTV channels and other local interference. What makes this software stand out over other intermod prediction software is the intuitive ease-of-use, ‘One Click’ group calculations, Click, Drag & Place spectral graphical representation, custom TX inventory profiles, DTV blocks, and stable reliability.
